Abstract

The paper deals with two different approaches for the analysis of electromagnetic field coupling to arbitrary wire configurations buried in a lossy medium: the wire antenna theory and the transmission line method. The wire antenna formulation deals with the corresponding set of Pocklington integrodifferential equation, while the transmission line model is based on the telegrapher’s equations. The set of Pocklington equations is solved via the Galerkin–Bubnov scheme of the indirect boundary element method, while the telegrapher’s equations are treated using the chain matrix method and finite difference technique, respectively. A number of illustrative computational examples pertaining to buried multiple lines and grounding systems is given in the paper.
